[llvm-commits] CVS: llvm/lib/Target/CBackend/Writer.cpp

[Anton Korobeynikov]

Changes in directory llvm/lib/Target/CBackend:

Writer.cpp updated: 1.269 -> 1.270
---
Log message:

Adding dllimport, dllexport and external weak linkage types.
DLL* linkages got full (I hope) codegeneration support in C & both x86 
assembler backends.
External weak linkage added for future use, we don't provide any 
codegeneration, etc. support for it.
